Objective:To evaluate postoperative biochemical and clinical remission rates in patients with unilateral primary aldosteronism and analyze related influencing factors.Methods:A total of 406 patients of primary aldosteronism with confirmed subtyping, who underwent adrenalectomy and completed follow-up in the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to March 2022 were retrospectively enrolled. Clinical and biochemical data were recorded. Postoperative clinical and biochemical outcomes were assessed according to Primary Aldosteronism Surgery Outcome(PASO) consensus.Results:Complete biochemical success was achieved in 391(96.31%) of 406 primary aldosteronism patients, while partial and absent biochemical success in only 4(0.99%) and 11(2.71%) primary aldosteronism patients; Complete clinical success was seen in 217(53.45%) patients, and partial clinical success in 189(46.55%) patients. Compared to the partial clinical success group, the complete clinical success group was younger, had a greater proportion of women, a smaller body mass index, a shorter duration of hypertension, a smaller daily defined dose value for antihypertensive medication, a higher estimated glomerular filtration rate(eGFR), and a lower proportion of family history of hypertension and diabetes mellitus. Multifactorial logistic regression analysis further showed that gender( OR=2.49, 95% CI 1.42-4.35, P=0.001), body mass index( OR=1.16, 95% CI 1.05-1.28, P=0.003), antihypertensive drug daily defined dose( OR=1.83, 95% CI 1.37-2.44, P<0.001), family history of hypertension( OR=2.16, 95% CI 1.22-3.83, P=0.008), history of diabetes( OR=2.47, 95% CI 1.15-5.29, P=0.021), and eGFR( OR=0.98, 95% CI 0.97-0.99, P=0.001) were independent factors influencing clinical prognosis of primary aldosteronism. Conclusion:The postoperative complete biochemical success is higher in patients with unilateral primary aldosteronism, but only about half of all patients achieve complete clinical success.

Objective:To investigate the appropriate cut-off for diagnosis of primary aldosteronism (PA) by seated saline suppression test (SSST) based on liquid chromatography with tandem mass spectrometry (LC-MS/MS).Methods:In this cross-sectional study, patients who underwent SSST for suspected PA in the First Affiliated Hospital of Chongqing Medical University from January 2018 to March 2022 were evaluated. Briefly, 300 patients with PA and 119 with essential hypertension (EH) were included. Plasma aldosterone concentration (PAC) after SSST was determined by LC-MS/MS. Primary aldosteronism confirmatory testing (PACT) score was used as the reference standard for diagnosis of PA, and receiver operating characteristic (ROC) curve was used to explore the cut-off value.Results:The average age of the PA group was (50.8±10.5) years, and males accounted for 53.00% ( n=159); the average age of the EH group was (49.4±11.2) years, and males accounted for 26.89% ( n=32). The area under the ROC curve of PAC post-SSST was 0.819 (95% CI 0.775-0.862). When 40 pg/ml (110.8 pmol/L) was selected as the appropriate cut-off for diagnosis of PA, the sensitivity was 83.67% (95% CI 78.88%-87.56%) and specificity was 60.50% (95% CI 51.10%-69.21%). Thus, 95.09% (155/163) of patients with unilateral PA could be identified. Conclusion:PAC after SSST determined by LC-MS/MS has high efficacy for diagnosis of PA, and 40 pg/ml is recommended as the appropriate cut-off value.

Objective To investigate the application value of dual-layer spectral computed tomography(DLCT)45 keV single energy image in follow up after transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC).Methods The DLCT images of 60 patients with HCC after TACE treatment were analyzed retrospectively.The CT value and standard deviation(SD)value of the lesion region of interest(ROI)and surrounding normal liver parenchyma on two kinds of images with 45 keV energy spectrum CT and 120 kVp conventional CT were measured respectively,then the contrast-to-noise ratio(CNR)between the lesions and surrounding normal liver parenchyma was calculated,and their differences were compared.The image quality of the two kinds of images was scored subjectively with the 3-point method,and the patients were divided into different groups according to the enhance-ment degree and tumor staining.The receiver operating characteristic(ROC)curve was also drawn.Results(1)There was no signif-icant difference in CNR between arterial phase,portal phase,and delayed phase of 120 kVp conventional CT(Hc=1.128,P>0.05).The CNR of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,with a statistically significant difference(Z=5.060,P<0.05).(2)The subjective score of 45 keV energy spectrum CT was higher than that of 120 kVp conventional CT,and the difference was statistically significant(Z=5.335,P<0.05).ROC curve analysis showed that 45 keV energy spectrum CT had a larger area under the curve(AUC)than 120 kVp conventional CT,and the difference was statistically significant(Z=4.136,P<0.001).Conclusion 45 keV energy spectrum CT image can significantly improve the CNR between tumor and normal liver parenchyma,and it has the better image quality and higher diagnostic efficiency.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia(ALSP)is a clinically rare autosomal dominant genetic disease,and its specific pathogenesis is not yet clear.The colony-stimulating factor 1 receptor(CSF1R)is a transmembrane tyrosine kinase receptor on the cell surface and mutations in the gene encoding it have been identified as potential pathogenic factors for ALSP.However,the specific mechanisms by which CSF1R gene mutations lead to the onset of ALSP are still unclear.After reviewing the mutation sites and pathogenic mechanisms of CSF1R in the pathogenesis of ALSP,CSF1R mutations have been shown to cause microglial dysfunction through mechanisms such as dominant-negative effects,loss of function,haploinsufficiency,and gain of function,thereby leading to the onset of ALSP.A deeper understanding of the causes of ALSP will help in exploring potential treatment methods.

Objective To observe the value of CT radiomics nomogram for predicting Ki-67 expression of thymus epithelial tumors.Methods Totally 163 patients with thymus epithelial tumor,including 114 patients in training set and 49 patients in validation set were retrospectively enrolled.The patients were further divided into low expression(＜50％)and high expression(≥50％)subgroups according to Ki-67 index.Multivariate logistic regression analysis was performed to screen independent predicting factors of Ki-67 expression in thymus epithelial tumors,and clinical-CT model was constructed.The optimal radiomics features were extracted and screened based on chest plain and venous phase enhanced CT images,respectively.Then radiomics modelplain and radiomics modelenhanced were constructed,and Radscoreplain and Radscoreenhanced were calculated,respectively.The nomogram model was constructed based on clinical-CT model,Radscoreplain and Radscoreenhanced.Receiver operating characteristic curves were drawn,and the area under the curves(AUC)were calculated to evaluate the efficacy of each model for predicting Ki-67 expression of thymus epithelial tumors.Results Patient's gender and enhanced CT value of lesion were both independent predicting factors of Ki-67 expression in thymus epithelial tumors(both P＜0.05).The AUC of clinical-CT model,radiomics modelplain,radiomics modelenhanced and nomogram model for predicting Ki-67 expression was 0.736,0.814,0.836 and 0.857 in training set,which was 0.746,0.746,0.750 and 0.799 in validation set,respectively.Conclusion CT radiomics nomogram could be used to predict Ki-6 7 expression of thymus epithelial tumors.

The typical manifestations of primary aldosteronism (PA) are hypertension with or without hypokalemia, high aldosterone, and low renal level. However, PA with normal blood pressure is rare in clinical practice. This article reported the diagnosis and treatment of a patient with subclinical PA, admitted for "adrenal accidental tumor" with normal blood pressure and serum potassium. We summarized and analyzed the clinical characteristics and treatment strategies, in order to provide some reference for clinicians.

Objective: Sex differences have been observed in many aspects of schizophrenia, including cognitive deficits. Despite extensive research into the relationship between metabolic factors and cognitive deficits in schizophrenia, few studies have explored the potential sex difference in their association. Methods: We recruited 358 schizophrenia patients and 231 healthy controls. The participants underwent measurements of body mass index (BMI), waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting blood glucose. Metabolic risk factors included abdominal obesity, hypertension, hyperglycemia, and dyslipidemia. A collection of these metabolic risk factors has been defined as metabolic syndrome. These diagnoses were based on the criteria of the National Cholesterol Education Program’s Adult Treatment Panel III. Cognitive performance was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). A descriptive analysis, difference analysis, and linear regression model were used to identify the metabolic risk factors for cognitive function in schizophrenia. Results: Our findings revealed sex differences in the rate of abdominal obesity and hypertension in schizophrenic patients. Additionally, we observed sex differences in the association between metabolic risk factors and cognitive impairment in schizophrenia. Specifically, hyperglycemia was associated with the immediate memory index score of RBANS in male patients, while dyslipidemia was associated with language, attention, delayed memory index scores, and RBANS total score in female patients. Conclusion Our results suggest that sex should be considered when evaluating the impact of metabolic disorders on the cognitive function of schizophrenic patients. Moreover, our study identifies hyperglycemia and dyslipidemia as potential targets for precise treatment by sex stratification, which could benefit the improvement of cognitive impairment in schizophrenic patients.

Objective:To test and evaluate the reliability and clinical effectiveness of osteoporotic thoracolumbar fracture (OTLF) scoring and classification system.Methods:A multicenter retrospective case series study was conducted to analyze the clinical data of 530 OTLF patients admitted to 8 hospitals including Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to June 2022. There were 212 males and 318 females, aged 55-90 years [(72.6±10.8)years]. There were 4 patients with grade C and 18 with grade D according to American Spinal Injury Association (ASIA) classification. According to the osteoporotic thoracolumbar injury classification and severity (OTLICS) score, all patients had an OTLICS score over 4 points and required surgical treatment. Among them, 410 patients had acute symptomatic OTLF (ASOTLF), including 24 patients with type I, 159 type IIA, 47 type IIB, 31 type IIC, 136 type IIIA, 8 type IIIB, 2 type IV (absence of neurological symptoms) and 3 type IV (presence of neurological symptoms), and 120 patients had chronic symptomatic OTLF (CSOTLF), including 62 patients with type I, 21 type II, 17 type III, 3 type IV (reducible under general anesthesia), 9 type IV (not reducible under general anesthesia), 1 type V (reducible under general anesthesia), 5 type V (presence of neurological symptoms), and 2 type V (not reducible under general anesthesia). Surgical procedures included percutaneous vertebroplasty (PVP), positional repositioning plus PVP, percutaneous kyphoplasty (PKP), posterior open reduction combined with bone graft fusion and bone cement augmented screw internal fixation, posterior open reduction combined with decompression, bone graft fusion and bone cement augmented screw internal fixation, and posterior open reduction combined with osteotomy and orthopedics, bone graft fusion and bone cement augmented screw internal fixation. A weighted Kappa was used to test the interobserver and intraobserver reliability of the OTLICS score, the ASOTLF classification, and the CSOTLF classification. The visual analog scale (VAS), Oswestry disability index (ODI), ASIA classification were compared before, at 1 month after surgery and at the last follow-up. Incidence of postoperative complications was observed.Results:The percentage of mean interobserver agreement for OTLICS staging was 93.4%, with a mean confidence Kappa value of 0.86, and the percentage of mean intraobserver agreement was 93.0%, with a mean confidence kappa value of 0.86. The percentage of mean interobserver agreement for ASOTLF staging was 94.2%, with a mean confidence Kappa value of 0.84, and the percentage of mean intraobserver agreement was 92.5%, with a mean confidence Kappa value of 0.83. The percentage of mean interobserver agreement for CSOTLF subtyping was 91.9%, with a mean confidence Kappa value of 0.80, and the percentage of mean intraobserver agreement was 91.3%, with a mean confidence Kappa value of 0.81. All the patients were followed up for 6-12 months [(9.0±2.1)months]. The VAS and ODI scores were significantly lower in patients with ASOTLF and CSOTLF classifications at 1 month after surgery and at the last follow-up than those before surgery (all P<0.05). The VAS scores in patients with ASOTLF types IIA, IIB, IIC, IIIA, and IV were significantly lower at the last follow-up than that at 1 month after surgery; the ODI scores in patients with ASOTLF types I, IIA, IIB, IIIA, IIIB and IV were significantly lower at the last follow-up than those at 1 month after surgery. The VAS scores in patients with CSOTLF types II, III, IV, and V were significantly lower at the last follow-up than those at 1 month after surgery, and the ODI scores in patients with all CSOTLF types were significantly lower at the last follow-up than those at 1 month after surgery (all P<0.05). Two patients with ASIA grade C recovered to grade D, and the rest recovered to grade E at the last follow-up ( P<0.01). No major vessel or nerve injury or internal fixation failure was found during follow-up. There were 18 patients with cement leakage, none of whom showed relevant clinical symptoms. There were 35 patients with new vertebral fractures, all of whom recovered well after symptomatic treatment. Conclusions:The OTLICS score, ASOTLF classification and CSOTLF classification have a high degree of reliability. Application of stepwise treatment for patients with different levels of injury according to the scoring and classification system can reduce pain, promote recovery of the spinal function, and reduce complications, which is of some significance in guiding the selection of clinical treatment.
